This article reviews the literature on intersex disorders, outlining the characteristics and mode of inheritance, if known, of each. For appropriate and effective management and counselling of patients and their families, physicians must have a good knowledge of the development of the genital tract and of the interaction between genetic sex and environmental influences.
